1. An apparatus for handling material comprising:
an elongated enclosure with side walls, a top portion with a top wall, and a bottom portion with a bottom wall, and having an inlet end for receiving material with an inlet gate and an outlet end with an outlet gate, the enclosure housing a sliding bed that separates the top portion from the bottom portion, the sliding bed comprising a plurality of slats extending laterally between the side walls from the inlet end to the outlet end, the slats being spaced apart, thereby forming openings between adjacent slats, and the slats having a leading edge and a trailing edge, with the leading edges of the slats overlapping the trailing edges of the next adjacent slat, and the slats being fixed in position and not rotatable with respect to the elongated enclosure, wherein the sliding bed is disposed at an acute angle declined from the horizontal in the direction from the inlet end to the outlet end; an air movement apparatus configured to generate a pressure differential across the sliding bed, with the pressure below the sliding bed in the bottom portion being higher than the pressure above the sliding bed in the top portion; a discharge plenum at the outlet end through the outlet gate, wherein the discharge plenum is configured to receive material exiting the enclosure; a dust outlet in communication with either the discharge plenum or the enclosure, or both, wherein the dust outlet is configured to direct lofted material exiting the enclosure to a desired location; and a collection apparatus in communication with the discharge plenum, wherein the collection apparatus is configured to collect non-lofted material exiting the discharge plenum. |
